A 93-year-old man suffering from dementia left viewers of new BBC series Hospital heartbroken after saying that he had forgotten everything apart from his late wife.

In the devastatingly sad clip, Ray Mitchell was seen sobbing as he reminisced about his wife, who died eight years ago.

Ray, who was staying at Nottingham University Hospital as social services tried to find carers to look after him at home, cried as he looked through pictures of his wife.

He said: "I've forgot most of the things now. I wouldn't forget her.

"I've always loved her, I'm just glad I married her. But what's the use of being alive when she's dead? In a way it's not worth living, is it?"

Also appearing on the programme was his daughter Julie, who said that the only time her dad really became lucid was when he talked about their mother. She added that he doesn't really remember the rest of his family.

Ray can't live alone and needs to be visited by carers multiple times a day after he lost his leg 10 years ago due to his diabetes.

He had returned to hospital after suffering a fall but had been waiting for 10 weeks for a care package to be put together before he was able to be released.

Despite being desperate to leave, Ray insisted that he did not want to go into a care home.

His consultant Rowan Hardwood agreed to Ray returning back home - despite the risk that he could fall over again.

"What we've got to think about is what he wants, what he's said in the past and what his family think is best for him," he said.

"There's a process to be gone through and decisions about whether somebody gives up their own home or goes home and takes the risks inherent."

Ray was finally able to go home and he had carers visiting him four hours a day to look after him and make sure that he took his medication.

Heartbreakingly, Ray returned to hospital in 24 hours after his carers discovered him in a bad way.

"Its like sitting with a shell he looks like my dad but he’s not my dad," his upset daughter said. "He’s lucid and he doesn’t know us because then he’ll start talking about my mum. It’s gone back as if he's a child now not a 93-year-old man."

Following doctors' advice that he needed 24 hour care, his family decided to put him into a care home after convincing him it was a rehabilitation centre.
